Hemispherical nanobubbles reduce interfacial slippage in simple liquids.

Physical chemistry chemical physics : PCCP

Finger A, Johannsmann D.
PMID: 21918764
Phys Chem Chem Phys. 2011 Oct 28;13(40):18015-22. doi: 10.1039/c1cp21548e. Epub 2011 Sep 15.

Using an electrochemical quartz crystal microbalance (EQCM), we have produced bubbles of nanoscopic size at the front electrode of an acoustic shear wave resonator. Nanobubbles are usually expected to increase the resonance frequency because they have a low density...

Method for fabrication of paper-based microfluidic devices by alkylsilane self-assembling and UV/O3-patterning.

Analytical chemistry

He Q, Ma C, Hu X, Chen H.
PMID: 23244032
Anal Chem. 2013 Feb 05;85(3):1327-31. doi: 10.1021/ac303138x. Epub 2013 Jan 07.

This work presents a novel and facile method for fabricating paper-based microfluidic devices by means of coupling of hydrophobic silane to paper fibers followed by deep UV-lithography. After filter paper being simply immersed in an octadecyltrichlorosilane (OTS) solution in...

Preparation of bismuth nanowire encased in quartz template for Hall measurements using focused ion beam processing.

Nanoscale research letters

PMID: 22958335
Nanoscale Res Lett. 2012 Sep 07;7(1):505. doi: 10.1186/1556-276X-7-505.

Forming electrodes on opposite sides of an individual bismuth nanowire was attempted to prepare for Hall measurements. Although a 1-mm-long bismuth nanowire which is completely covered with a quartz template has been successfully fabricated to prevent oxidation, it is...

Real-time assessment of cigarette smoke particle deposition in vitro.

Chemistry Central journal

Adamson J, Hughes S, Azzopardi D, McAughey J, Gaça MD.
PMID: 22958446
Chem Cent J. 2012 Sep 10;6(1):98. doi: 10.1186/1752-153X-6-98.

BACKGROUND: Recently there has been a rapid increase in approaches to assess the effects of cigarette smoke in vitro. Despite a range of gravimetric and chemical methods, there is a requirement to identify simpler and more reliable methods to...

Differential solute gas response in ionic-liquid-based QCM arrays: elucidating design factors responsible for discriminative explosive gas sensing.
